cds-question@unistra.frstandard-starsvisible-astronomyspectroscopySpectra are presented for MK standards in the wavelength range 580-1020nm. The stars cover the normal spectral types O to M and luminosity types I, III, and V. In addition, a small number of peculiar stars are included. The data are in 137 FITS files, in the "fits" subdirectory. The list of the 137 stars is included in the "stars.dat" file; note that the list is not identical to the stars listed in Table1 of the paper. Introduction: The projected slit width along the dispersion was about 4{AA}, slightly less than 2 pixels. The data are corrected for atmospheric extinction. The fluxes are relative; to convert to "absolute" the values should be multiplied by 10-13erg/cm2/s/{AA} (10-15W/m2/nm) but because not all of the flux was collected by the slit, these values will be about 15% low with the factor depending on the seeing. Some features in the spectrum have been introduced by the instrumentation. The most notable feature is a small emission peak near the NaI 5896{AA} absorption line. The data are in FITS format. The FITS header does not include the units, which are described above. The spectral types and luminosity classes given in the published paper supersede those given in the FITS headers.1994PASP..106..382Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/III/179CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=III/179https://vizier.iucaa.in/viz-bin/VizieR-2?-source=III/179http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=III/179https://vizier.cds.unistra.fr/viz-bin/votable?-source=III/179https://vizier.iucaa.in/viz-bin/votable?-source=III/179http://vizieridia.saao.ac.za/viz-bin/votable?-source=III/179GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table III/179/stars (*List of stars present in the "fits" subdirectory)https://vizier.cds.unistra.fr/viz-bin/conesearch/III/179/stars?https://vizier.iucaa.in/viz-bin/conesearch/III/179/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/III/179/stars?GETtext/xml+votable180.050000true120.895833-40.0030560.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=III/1796/79 155 463 472 474 689 754 6377 12544 12604 12766 12864 12962 17085 17185 17197 17322 17397 17608 17754 18276 18498 18702 18978 18998 19045 19309 19312 19417 19467 19585 19912 20012 20178 20759 20797 20847 20862 20915 21089 21112 21401 21438 21788 21879 22787 22790 22798 22807 22822 22837 22854 22911 22964 23007 23230 23360 23369 23431 23523 23538 23621 23637 23820 23864 23998 24048 24144 24151 24164 28793 28890 29155 29390 29800 30475 30491 30505 30529 30543 30616 30709 31756 31776 32192 33044 33585 33919 33976 34356 34577 34817 35045 35374 35676 35756 36693 36697 36711 36757 36850 38018 38026 38074 39088 39125 39247 39327 39427 39436 39520 39582 39789 39818 39831 39868 39907 39923 40486 40692 42334 42948 42977 44305 44366 45530 46367 46566 46571 46776 47991 48344 49049 49060 491233.322582951404819e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/III/179?format=asciidefaultIII/179/stars*List of stars present in the "fits" subdirectoryrecnoRecord number assigned by the VizieR team.
